Old Rag Mountain Quilt (0F)

(13 customer reviews)


Conservatively rated to 0°F (-17° C) the Old Rag Mountain Quilt can be used either as a top quilt (in a hammock or on the ground) or as a hammock under quilt (JRB Suspension System sold separately).

Over-stuff: 25% over-stuff included!

Compression Sack: For 0 degree quilts we recommend the large size compression sack.



Old Rag Mountain winter hammock quilt is lighter than a sleeping bag. No squirming around to get in and out. Easy to vent for temperature control. The Jacks’ first down quilt, the “Old Rag Mtn” is a true winter quilt capable of keeping a sleeper warm down to 0°F(-17°C). “The Old Rag Mtn” was specifically designed for use as a top quilt with a foot sack capability and can be used either on the ground or in a hammock. It will also function as a hammock under quilt (JRB Suspension System sold separately). For individuals over 5 feet 10 inches tall we offer a long version (86″ in length).

Over-stuff: 25% over-stuff included!

All Jacks ‘R’ Better quilts are overstuffed by at least 25%. We do not recommend additional over stuffing. If you think you need additional over-stuff consider purchasing the next warmer quilt model.

Compression Sack: A lot of folks no longer use compressions sacks and instead keep their quilts dry inside a lawn contractor bag or trash compactor liner.  We do not want anyone to have to pay for something they do not want so now we offer them separately. For 0 degree quilts we recommend the large size compression sack.

The Old Rag Mountain Winter Hammock quilt works as a  top quilt or underquilt for ENO Hammocks, Hennessy Hammocks, Warbonnet Hammocks, Dutchware Chameleon, as well as most other brands and DIY hammocks.

Activ-dri down™ – Activ-dri™ is a hydrophobic down treatment that keeps the down drier, while having no adverse effects on loft, fill power, or warmth retention. Activ-dri down is still down insulation and should be protected from direct exposure to moisture. All types of insulation, whether down or synthetic, will degrade in insulation capability if wetted.

    Great quilt for backpacking and hammocking. Really lightweight with a good temp rating for it’s weight. I’m actually able to wrap the quilt all the way around my hammock so that it acts as an underquilt and overquilt. I still have to use a sleeping pad to block the wind, but it works great. It would be cool to see a quilt that’s a little wider with velcro all the way up and down it, so you could get it all the way around your hammock and seal it up. Maybe that would add too much weight though

    I am 5’8″ tall and the regular length is definitely large enough and then some. Have used the quilt two times so far in temperatures in the low 20’s and it was actually a little too warm. So I believe that it will definitely come close to be warm down to the rating that is posted. The quilt is well made and packs relatively small for the amount of down.

    I love my Old. Mtn Rag, but I am a gearhead. I am always looking around for something better, or maybe even just something different. I think I have tried different items for everything except for my tarp and my quilt: different stoves, base layers, insulation, backpacks, etc. But I have never found an alternative to my Old Mtn Rag despite looking for over 6 years. It needed wings, and Jack R Better shipped me the fabric to add them. The temp range works well for me in the high Cascades. I will keep looking, but I doubt I will every find something I like better.

    Got my Old Rag for Christmas 2014 to go with my Nest. I could not be happier. The fit and finish are perfect. I use as a top quilt for the hammock and also with my SynMat 9 when I am on the ground. Either way, the quilt does it’s job and I stay toasty warm.

    Phenomenal quilts. Purchased 1 of these in “long” to use as a TQ with hammock pod system. Upon arrival loved the size, loft, warmth, and versatility so much I purchased a second to use as full length UQ. Took them on a trip to Michigan for some cold weather hammock camping with a 20 degree bag and they did not let me down. Temps got down to 2 degrees and I was completely warm. Second night temp was 18 degrees and I was too warm and had to vent my bag. By comparison, I had used just the bag and sleep pad a week before at 1 degree and was uncomfortably cold. I highly recommend these for their performance and versatility. JRB service is outstanding as well. When ordering the second, I called Jack last minute on a holiday Monday needing it to arrive Thursday. He answered, took my order and made sure I would receive it on time. I look forward to using these for years to come. Thanks!

    Owned my rag for 6 years now. It’s taken me to 7 degrees along with my Mt Washington 4 underquilt. No pad. Best customer service. Pan and Smee are what anyone wants when it comes to responsiveness.

    Dad told me once if somethings really good get two….so I did despite the cost… but I tell you what … I have a sewing machine I sew better then some and worse then most, making tarps and over/under covers is about as far as my skill level goes.
    I brought one on a on an overnight. I ended up soaked. I was grounding it in my SMD solo, and it poured buckets for 8 hours. I had to strip to my skibs and was about 56 degrees. I was so thankful to have this quilt. It really saved my ass literally. Note I did have mid level StS liner. The quilt never lost loft and seemed bone dry.

    As for hammoking this line of quilts is unbeatable in terms of versatility. From ground use to over and underquilt mode it can’t be beat.
    The quilt is extremely well made and a absolute MUST have for any camping system.

    The fact they are smart and stock ahead is brilliant and reflects the business. Every place I checked had a lead time of no less then 4 weeks….thats unacceptable in today’s market. If you’re going to make a product to order (unless modded) you may as well keep your stuff off the Internet and sell at local flee markets to keep up with volume. Ppl don’t wanna wait 4-12 weeks when they drop a few hundred on something…. imo.

    One last thing

    I just came back from my first winter hang. Lowest temp at night was 28 degrees (was hoping it would be colder). I purchased the Old. Mtn Rag along with the Greylock 4. Talk about being in down heaven! I was so comfortable and warm, not to mention the secure feeling knowing I was not going to be cold at any point. I couldn’t have made a smarter decision pairing these two quilts together! Extremely satisfied and happy camper here! Thank you, for making such wonderful gear!

    I really wish this quilt performed for me as well as it as other reviewers have noted.

    I’ve owned this quilt for around a year now and I feel confident in these particular pro’s and con’s over a wide range of uses and temps.

    The quilt is quality constructed and filled with a significant amount of high quality down. It’s also available off the shelf!!! Not many quilt manufacturers offer this and it can mean the difference between a last minute trip. It performs really well in temps to around 30°F and honestly that’s it. It would make a great option for a thru hike on certain trails as I’ve found it to be resistant to condensation and dries quickly, while still allowing for venting when needed. I own the enclosed footbox regular version in 800FP. I think given the price this is a great option for a lot of ranges and a lot of different people.

    I have used in temps down to around 20°F and find it impossible to stay warm in. Even with adjusting the loft (I never compress it, instead leaving it stuffed loosely in my bag and totally flat in a storage room), inside a bivy (Bristlecone), with a light down jacket on and on a pad rated to 15-25°F. I find it difficult to attach to a pad, or stay completely flat on my back to keep heat in. This brings up a LOT of cold spots in my torso area and a restless nights sleep. Now I’m also a very slim/athletic built female. 5’5 and 115lbs, give or take at times. I was at first concerned that my body size may create dead air, it doesn’t and I’m able to close in enough heat with the footbox being sewn and stuffing/wearing clothes as needed. I just think this quilt should have some extra down in the top half, maybe a different/vertical sewing design to keep the down from shifting, a draft collar and definitely a better attachment system/points for ground sleepers. I suggest editing the temperature rating and perhaps incorporating a conservative woman’s rating as well.

    In the end I would recommend this product, just not for the temps it’s advertised for and offer adjustments to the basic design for ground dwellers.

    After a year on my MW4 I decided to up my game on a top quilt replacing my beloved 21 y.o. TNC Chrysalis that has served me well despite blowing out the zipper some 10 years ago and only being a 40d bag.

    While it worked OK as a TQ and will remain in the stable, I have aspirations for extending my 3+ season mostly car camping hangs into some whiter fluffy weather, or possibly less layering in the beginning or ends of my season.

    With a year on the MW4 UQ and 1st hand experience on the quality/performance I had no reservations picking up the ORM as a great match for the cold weather setup.

    A recent cold snap in Michigan gave me my 1st chance setting a new low of 37, previously a lightweight 47. I only added a hoody to my normal wool socks, felt type pj pants, and tee.

    Despite having to get up for numerous nature calls, climbing back into that down footbox and spilling loft was immediately welcome. I’m a cold sleeper being and a small guy I doubt any bag/quilt is going to go the distance solo as rated, but I’m 100% satisifed with this addition. The bar is set high for longevity so only time will tell, but this may well be the last down heaven I’ll ever have to buy.

    It’s nice to see the addtional colors being offered although I didn’t have a problem with the long standing JRB green. I didn’t really notice from the swatch and assumed it’d be the same, but mine came in a more olive drab so now I can tell what’s what when setting up (altho they could obviously go either way as TQ/UQ).

    There’s lots of quality cottage style gear out there and I like to spread my purchases/support out to give everyone a chance. JRB has already proven they get a spot on that list.
